Vintage 1960’s 1970’s slim skinny plaid shorts red white blue 37 patriotic

Great pair of vintage slim cut plaid leisure shorts in red white and blue. Tags are worn off so maker and size are unknown. Waist measures 38 but it’s a little stretched out so we are calling these a size 36. Inseam is 7.5 and leg opening is 11 inches. Great vintage style.
